CHECKING BATTERY CONDITION
Precautions
CAUTION
BATTERY PRECAUTIONS
The battery produces flammable and explosive
hydrogen gas.
 Do not cause a spark by contacting the battery
terminals with tools.
 Do not smoke or light a match near the battery.
The electrolyte contains poisonous and corrosive
sulfuric acid.
 Avoid contact with eyes, skin or clothes.
 Never inhale or swallow electrolyte.
 Wear protective safety glasses when working near
the battery.
 Keep children away from the battery.
EMERGENCY MEASURES
 If electrolyte gets in your eyes, flush your eyes with
clean water immediately and get immediate medical
attention. If possible, continue to apply water with a
sponge or cloth while traveling to the medical office.

ELECTRICAL COMPONENTS
602
If electrolyte gets on your skin, thoroughly wash the
contacted area. If you feel a pain or burn, get medical
attention immediately.
 If electrolyte gets on your clothes, there is a
possibility of its soaking through to your skin, so
immediately take off the exposed clothing and follow
the procedure above, if necessary.
 If you accidentally swallow electrolyte, drink a large
quantity of water or milk. Follow with milk of
magnesia, beaten raw egg or vegetable oil. Then go
immediately for emergency help.Checking battery exterior
1Terminals2Holddown clamp
Check the battery for corroded or loose connections,
cracks, or loose holddown clamps.
1. If the battery is corroded, wash it off with a solution of warm
water and baking soda. Coat the terminals with grease to
prevent further corrosion.
2. If the connections are loose, tighten the clamp bolts — but
do not overtighten.
3. Tighten the hold −down clamp only enough to keep the
battery firmly in place. Overtightening may damage the battery
case.
